Application September 29, 1941, Serial No. 412,895

1 Claim.

The main object of the present invention resides in the improved type ofbearing by which the roller members are rotatably connected to the doorsupporting bracket.

Another object of the invention is the provision of a longitudinallyextending elongation on the supporting bracket or shank which assuresthe proper alignment of the rollers within the supporting trackway.

A further object of the present invention resides in the connectionbetween the lower end of the supporting shank and the upper surface ofthe door.

While in the attached drawing, I have shown my invention in itspreferred form it will be obvious to those skilled in this art, that itis not to be considered in such a limited manner, but is susceptible ofvarious other changes and modifications, without departing from thespirit thereof, and I desire, therefore, that only such limitationsshall be placed thereupon as are imposed by the prior art, or as arespecifically set forth in the appended claim.

Referring more in detail to the attached drawing, wherein similarletters of reference refer to like parts throughout the several views:

Figure 1 is a transverse sectional view taken through a section of aWall and showing the hanger in its supported position within a channeledheader and with a door indicated in section suspended from the lower endof the shank of the hanger;

Figure 2 is a side elevation of the hanger with one of the rollerelements omitted to better illustrate the bearing assembly and with adoor in fragmentary section and its connection with the lower end of theshank;

Figure 3 is a transverse view partly in section on line 3-3 Figure 2looking in the direction as indicated by the arrow;

Figure 4 isa top plan view of the door plate with the bracket shank insection;

Figure 5 is a View of the inner face of one of the roller elements;

Figure 6 is a longitudinal view of the bearing pin on which the rollersare rotatably mounted and showing one end of the roller pintle insection;

Figure '7 is a side elevation of a modified type of hanger connection toa door and Figure 8 is an end elevation with the lower end of thesupporting shank in section to better illustrate the socket for thereception of the enlarged end of a screw or similar headed member.

In the drawing I have used my composite type of header which forms thesubject matter of my oopending application Serial No. 412,894, filedSept. 29, 1941, but it is to be understood that any type of double facedtrackway may be employed. The header as shown is constructed ofwood, theupper sections I0, I I, and I2 being of a relatively light and cheapergrade of stock while the track portion I 3 is of a harder grain orstructure. This header is provided with an internal trough or passagewayI4 and with a longitudinal slot I 5 heading from the lower face of theheader to the passageway I4.

The door hanger which is the essence of the present application has ashank I6, the medial portion of which is longitudinally extended toprovide an elongation I'I. This elongated area or surface performs arather useful purpose in the proper assembly of the door hanger into itsdesired position in the trackway of the header. The cross area of theslot I5 will permit the reception of the shank only when the area I! islongitudinally disposed therein, thereby assuring that the rollerelements will be correctly positioned on the internal trackway.

The upper end of the shank I6 is provided with a cylindrical head I8which is longitudinally bored as at I9 for the reception of the rollersupporting shaft. This shaft has an enlarged cylindrical portion 20which snugly fits within the bore I9 and extending at either sidethereof is a roller supporting pintle 2I-2I. It should be noted herethat the ends of the enlarged portion 20 extend slightly beyond theouter faces of the cylindrical head I 8-as indicated at 2222, all for apurpose as will hereafter appear.

The roller members 23-23 are of semi-spherical formation as shown andhave internal ribs 24 for the purpose of rigidity. The central portionof each roller has a bored hub 25 which is adapted to fit over one ofthe roller supporting pintles 2|. The ends of the pintles 2| are boredas at 26 so that the pintle ends can be readily spun or pierced torigidly fasten the rollers to the pintles and thereby lock both rollersfor uniform rotation. In so fastening the rollers to the pintles it willbe appreciated that the inner face of the rollers will be forced intoengagement with the extended portions of the cylindrical enlargement 20,which will effectively space the roller from direct contact with thecylindrical head l8.

The lower end of the shank as shown in Figures 1, 2, 3, and 4 has anenlarged head 21 which fits into a slotted door plate 28, being retainedtherein when seated within the recessed portion 29 which snugly receivesthe head 21.

In the modified form of door connection as shown in Figures 7 and 8 thelower end of the shank is provided with a socket or recess 29' and isslotted as at 30 to receive the headed portion of a screw 31 or similarheaded member. As shown the screw 3| is attached to the top surface ofthe door and is driven therein, leaving just the amount of clearance tosnugly engage in the socket 30.

The door in this case is inserted into proper position to engage withthe lower end of the depending shanks by a transverse movement withinthe door opening as fully set forth in my copending application andfurther as disclosed in my prior Patent 2,207,322, July 9, 1940.

What I desire to secure by Letters Patent is:

A door hanger of the class described compris ing in combination avertically extending shank having a roller supporting structureassociated with the upper end thereof, the lower end of the shank havingan inwardly extending recess formed in the body portion thereof, and ascrew secured to the top edge of a door with the head of the screwspaced upwardly therefrom, said screw head adapted to be received withinthe recess in the shank to hold the door in suspended position from thelower end of the shank RALPH L.
